Sounds counterintuitive, doesn't it? But a group of researchers at Stanford University modified commercial solar panels to commercial solar panels to generate power at night.Through a process known as radiative cooling. radiative cooling (when a body loses heat through thermal irradiation). In this case, the Stanford researchers take advantage of the cooling process of the solar panels after the sun goes down to generate electricity with a thermoelectric generator that works from the temperature difference in the panel and that of the outside air and that, moreover, is low-cost. low cost.

It generates small amounts of energy, but is a technology that can be improved to generate up to 20 times more electricity than that obtained in than that obtained in tests. This innovation can be used in low power density applications, such as night lighting, recharging devices or powering online monitoring equipment. night lighting, recharging devices or powering online monitoring equipment, and is especially useful for isolated areas. and is especially useful for isolated areas or remote installations.
